The Grand Canyon Skywalk Dispute

The Grand Canyon Skywalk was the brainchild of Henderson businessman David Jin. He partnered with the Hualapai Tribe, which owned prime land on the rim of the canyon and the tribe agreed to the construction of the glass-bottomed horseshoe that extends out over the canyon. It's a successful tourist attraction but has no visitor center or gift shop or bathroom facilities. The project has been mired in an acrimonious dispute for months and now the Hualapai have taken it over with eminent domain. So what happens now? And how far do the sovereign rights of the tribe extend?
